ILLINOIS, -A CORPORATION OF ILLINOIS CHAIR Thisinvention relates to improvements in' chairs and it consists of the matters herein- 7 after described and more particularly pointed out in the appended claims. v

The primary object of the invention is to provide achair especially adapted for airlane use, which chair though light in weight isindeed strong and at the same time is comfortable and easy fortheoccupant and may be made at a substantially low cost of production. v

Another object of the invention is to provide a chair of thiskind having a frame Work made up of lengths of light weight tubing so formed and welded together as to cooperate to the best advantage in forming a chair having all characteristics desired for one employed in airplane work.

Theseobjects of the invention as well as '20 others, togetherwith the many advantages ,thereof will more fully appear asI proceed with my specification.

In the drawing Fig. 1 is a perspective view of a chair em bodying my invention.

Fig. 2 is a perspective view of the chair.

, with the seat cushion andupholstery removed to better illustrate the structure of the welded tubular frame and associated. seat bottom.

3 Fig. 3 is a detail transverse vertical sectional view on an enlarged scale throughone side of the seat frame and associated parts as taken on the line 33 of Fig. 2.

Fig. 4 is a detail vertical sectional view also 7 on an enlarged scale through the front portion of the seat frame and associated parts as taken on the line il-41 ofFig. 2.

Referring now in detail to that embodiment of the invention illustrated in the accompanying drawing :1 indicates as a whole H the frame of the chair which is preferably made up entirely of thin light metallic tubing of substantially small diameter. Said frame includes substantially upright front legs 22 and substantially upright rear legs 1 3-3, the front legs each having a rearwardly extending substantially horizontal portion 4 that is welded to the rear legs to provide the side rails of the frame. The front legs as 9 well as the rear legs are provided at their said rear legs near the feet thereof, the crotch.

bGlIlg welded at their ends to said upright the rear leg extensions 11 meet with and are bottom ends with horizontally bent extensions or feet 5 whereby stability is provided for the frame as well as a means of attaching the chairin place to the floor of the cabin or cockpit, of an airplane.

Associated with the front legs is an inverted V-shaped brace the bottom ends of thediverging arms 6 of'which' are'welded to the front legs near the feet thereof, the'crotch or apex 7 of said brace being positioned substantially fiush'with' the top ends of'said front legs. Associated with the rear legs is an inverted V-shaped brace, the bottom ends of the diverging legs 8 of which are welded to 9 of the brace being disposed in substantially the plane of the attachment of the rails 44 with said rear legs. p a

The front legs are pitched slightly rearwardly at their top ends toward the rear while the rear legs which are pitched slightly for- Wardly, include upright extensions 11, that form those portions of the frame providing a back rest for the chair. The top end of each extension is connect-ed to the bottom portion of the other extension by a diagonal brace bar 12, the two bars crossing each other to give an X'-shape thereto andbeing welded together at their point of intersection and extensions as best shown in Fig. 2.

13 indicates as a whole an inverted U- shaped member including side bars 14 -14 and a top crossbar 15. The top ends of welded to the said cross bar 15 while the legs of said U-shapedmembers extend downwardly and forwardly, toengage and be Welded to the outside of the horizontal rail portion and to the bottom end of an associated front leg 2. A brace 14 connects the bottom end of each rear leg, with the associated leg 14 of said U-shaped member at a point approximately in theplane of the portions 4 before mentioned. The side bars l t-14 of 5 said U-shaped member not only brace the back rest members but also provides the side arms for the finished chair.

Associated with the frame thus far described is a seatbottom 16 including an open frame comprising side rails 17 and front and rear rails 18 and 19 respectively all preferably of wood, the frame being normally closed by a panel like seat bottom 20. When the seat bot-tom is in place upon the frame before described, the front and rear rails thereof engage upon and are secured to the crotches 7 and 9 respectively of the inverted V-shaped braces before mentioned by bolts 21 and 22 respectively, while theside rails of the seat frame rest upon the horizontal rail portions 4- of the front legs and are secured thereto by bolts 23, 2st and 25 respectively. In this respect it is pointed out that each side rail of the seat frame-is provided 7 with a notch or recess 26 to accommodatethe v like and a deep seat cushion 28 is provided side bars 14: of the U-shaped members before mentioned.v

' The frame thus farrdescribed is enclosed in asuita-ble covering of fabric 27 or the of an airplane, its feet may be securely attached to the floor thereof in any suitable manner. a 1 e The construction described provides a strong light weight chair especially adapted for airplane use, and one that cannot be easily racked or twisted out of shape or become loose at any of the connections between the associated parts. Again, the :chair is com-- fortable for the occupant.

While in describing the invention, I have referred in detail to the form, arrangement and construction of the parts thereof, the same is to be considered merely as illustrative so that I do not wish to be limited therer to except as may be specifically set forth in the appended claims.
